Jermain, a NCS ambassador, also spoke of the life-changing impact the service had on his life. The NCS provides 15 to 17-year-olds with the chance of working on community projects close to their heart. This enables them to develop essential skills for work and life.

He was one the first to complete the NCS programme in London in 2012.

Given the nickname “the singing politician” by The Voice judge Sir Tom Jones, Jermain was presented with his NCS award by David Cameron at Downing Street, when he told the Prime Minister: “Watch your job, I’ll be taking it soon.”

The singer said: “The last few years have been an incredible journey for me and I wanted to be able to share some of these experiences with students at Ninestiles who are looking ahead to their own futures. For me, taking part in NCS in 2012 was a defining moment, helping me to develop the confidence to realise my ambitions. It was an experience I’d encourage everyone to say ‘yes’ to!”

Londoner Jermain - the first male Voice winner - is tipped to be the show’s first big star. Coached by will.i.am, the 20-year-old scooped a £100,000 record deal as first prize.

His ambitions do not stop at topping the charts, however. Jermain wants to go down in history as the first singing Prime Minister.
